The Aerobic Respiration Equation |
Glucose + Oxygen ------> H20 + Energy + CO2 |
|
|
How much ATP is produced per glucose molecule in aerobic respiration? |
38ATP |
|
|
What is 'Glycolysis'? |
Glycolysis is the first stage of respiration and it does not require oxygen. It is the breakdown of the sugar glucose molecule, through a series of enzyme-catalysed reactions, into two molecules of pyruvate. |
|
|
Describe the 'energy investment phase' of Glycolysis. |
Energy from 2 ATP molecules is needed to start - in order to phosphorylate intermediates. |
|
|
Describe the 'energy pay off phase' of Glycolysis. |
The production of other intermediates eventually regenerates 4 ATP molecules. This results in a net gain of 2 ATP molecules throughout the whole stage of Glycolysis. |
|
|
Where does Glycolysis take place? |
In the cytoplasm. |
|
|
What is the purpose of dehydrogenase enzymes in Glycolysis? |
To release hydrogen ions and high energy electrons which then combine with a coenzyme called NAD in order to form NADH. |
|
|
Where does the Citric Acid Cycle take place? |
In the matrix of the mitochondrion. |
|
|
What is the Citric Acid Cycle? |
The Citric Acid Cycle is the second stage of respiration and it only occurs if oxygen is present. |
